humerus and the ulna and is inserted into the pisiform and the 

 fifth metacarpal bone. 



The extensor digit, long, (radialis subl. ?) goes to digits 3-5. 



The " extensor dig. minimi projirivs " ends by three tendons on 

 digits 3-5 (1st phalanx). 



The ext. indicis et polUcis comes from the distal end of the ulna.

The '■' palmaris longus" arises (very broad) from the internal 

 condyle (hum.) and ends by four tendons (connected with each 

 other) on digits 2-5, some fibres going to the Pp. and to the 

 neighbourhood of the Pm. 



As this muscle has two nerves (from the medianus and the 

 ulnaris) it may perhaps be considered as formed by union of two 

 palmares.

There are strong nerves and vessels running to the Ph. 



The gastrocnemius consists of two separate muscles arising from 

 the inner and the outer condyle of the femur, joining each other 

 only on the insertion on the calcaneum. 



The plantaris takes origin in common with the lateral gastro- 

 cnemius, runs down, crossing the tibial or inner gastrocnemius at di,n 

 acute angle ; it is fixed on the calcaneum and ends in the " fascia " 

 plantaris, the tendinous fibres going mostly to the Ph.
